Research Abstract

The project "Decoding Earth Evolution Program" have aimed to decode the history of the Earth ranging 4 billion years from the deep sea sediments as the recording tapes of the Earth's environmental change. Three years research have gave the establishment of many kinds of new methodology as well as fruitful results as follows.
1) We have carried out field survey at South Africa, Western Australia, and Namibia, and collect great amount of specimens of deep sea sediments and volcanic rocks. For the sampling of the deep sea sediments, we developed new methodology to collect samples as continuous as possible.
2) We have developed new technology which will be basic and key technology in many fields in earth and planetary sciences. The laser-ablation ICP-MAS have been developed to determine absolute U-Pb age of single zircon grain. XRF image analyzing system have developed to construct image database of deep sea sediments and high resolution chemical profiles from which the rhythms and events of earth environment will be detected.
3) We analyzed the samples in so many items. For example, we detected fluid inclusion of the volcanic rocks at ancient ridge form which the state of water circulation and CO2 content of atmosphere in Archean earth was deduced. We detect a event layer in the oldest BIF from Isua, Greenland, in which Iridium is concentrated suggesting the oldest impact events record.
